In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.

Ozone breaks up filaments and improves settling characteristics of the sludge...
Filamentous sludge is a common problem at activated sludge plants. With ozonation of the return sludge flow it is possible to reduced the amount of filamentous bacteria in the sludge and significantly increased the settling properties of the sludge.This in turn means better performance of the activated sludge process.
When a bioreactor is connected to the sludge line the removal of the damaging filamentous bacteria means higher...

Federal and State regulatory agencies are increasingly requiring additional water quality testing and controls of the toxicity of discharges to receiving streams. Granular Activated Carbon (GAC) helps meet these pollution regulations. If organic chemicals have been identified as contributing to discharge toxicity, Calgon Carbon Corporation can work with facilities, and their engineering firms, to help meet stringent criteria associated with their NPDES permit. GAC can be employed as a cost-effective treatment for...

You refine the fuel, we’ll remove the odors. Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the oil industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public. Ecosorb odor removal products may be used in a variety of areas around the refinery including...

TenCate Geotube technology provides cost-effective and sure dewatering and containment in a wide variety of industries. In Power and Utility, Pulp and Paper and other general industries that produce sludge, TenCate Geotube dewatering technology enables the recovery of valuable materials, provides structural stability, improves water quality, or just reduces storage footprint by sometimes 50 to 80%. The dewatering containers can be custom-sized to the application, placed in available space between...

Sustainable metal recovery and water treatment. The metal and mining industry is increasingly aware of the opportunities to recover valuable resources from process and bleed streams. This combines creating revenues with environmental sustainability. The traditional method of removing dissolved metals and sulphate from aqueous process- and waste streams in the metal and mining industry is by neutralization with an alkaline agent like lime. The gypsum and metal hydroxides which are produced in this process...

When used to suppress toxic vapors and break down tank sludge, iSorb is a safe and reliable treatment before removing or maintaining underground and above-ground tanks. iSorb supports safe working conditions, minimizes tank downtime, and reduces waste-handling and treatment.

VITONE ECO decanters, together with all auxiliary machinery such as polypreparers, removal dewatered sludge screws, pumps, etcetera, are meant for the following uses: dehydration and thickening of sewage from civil and industrial purification plants; dehydration of vegetable biomasses and zootechnical sludge; waste water treatment for distilleries and fellmongering waste.

ENTACT is the industry leader in the management and treatment of heavy metal impacted soil, sludge, and debris. Approximately half of the projects we have completed over the past 21 years have involved metals. These projects have included soil and sediment removal, residential cleanups, smelter closures, earthwork/mine reclamation, and decontamination and demolition of mine and mill structures at both active and abandoned facilities. ENTACT holds seven patents related to treatment of heavy metal impacted materials.

Respiration rate of activated sludge has been recognised as a key controlling element in the modelling of process control, by the International Water Association Task Group. Actual respiration rate of the sludge in the aeration tanks, as well as the endogenous and maximum respiration rates are variables that indicate the rate of BOD removal and aeration requirements. The maximum respiration rate is also closely linked to the Critical Oxygen Concentration point, that is, the point at which diffusion over the...
